Solvers that support inductive definitions have been developed, but several of their computationally nice properties have never been exploited to improve these solvers. In this paper, we present a new notion called relevance. We determine a class of literals that are relevant for a given definition and partial interpretation, and show that choices on irrelevant atoms can never benefit the search for a model. We propose an early stopping criterion and a modification of existing heuristics that exploit relevance. We present a first implementation in MinisatID and experimentally evaluate our approach, and study how often existing solvers make choices on irrelevant atoms.","doi":null,"url":"https://ijcai.org/proceedings/2016/91","pdf":"https://ijcai.org/proceedings/2016/0091.pdf","markdown":"https://ijcai.org/proceedings/2016/91.md","bibtex":"https://ijcai.org/proceedings/2016/bibtex/91","volume":{"slug":"2016","title":"Proceedings of the Twenty-Fifth International Joint Conference on Artificial Intelligence","short_title":"IJCAI 2016","url":"https://ijcai.org/proceedings/2016/","year":2016,"location":"New York, NY, USA","dates":"9–15 July 2016","editors":"Subbarao Kambhampati","isbn":"978-1-57735-770-4; 978-1-57735-771-1","publisher":"AAAI Press / International Joint Conferences on Artificial Intelligence","doi_prefix":""},"section":null,"track":"","number":91,"pages":{"first":596,"last":601},"keywords":[],"videos":[],"references":[],"license_note":"Copyright International Joint Conferences on Artificial Intelligence."}
